MECHANISM FOR TRANSMITTING POWER FROM VEHICLE GROUND-WHEELS.

SPECIFICATION forming part of Letters Patent No. 696,642, dated April 1, 1902. Application filed December '7, 1901. Serial No. 84,989. (No model.)

To (all whom it may concern.-

Be it known that I, CLEMENT L. V. KINNEY, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented a certain new and useful Improvement in Mechanism for 'Iransmitting Power from Vehicle Ground-Wheels, of which the following is a specification.

My invention relates to the improvement of power transmission from vehicle-wheels; and the objects of my invention are to provide an improved construction whereby rotary motion is transmitted to a sprocket or belt wheel through the rotary traveling motion of a vehicle ground-wheel; to provide improved connections between a vehicle or wagon groundwheel and a sprocket, belt, or other powercontributing wheel which will facilitate the running of mechanism carried bysaid vehicle; to provide improved means for insuring the proper engagement of the teeth of the operating ratchet-wheel and ground-wheel pawls or dogs, and to provide other improvements, the details of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which Figure 1 is an outer face view of a vehicle ground-wheel having my improvement thereon. Fig. 2 is a View in elevation of the ratchetwheel which I employ in the manner hereinafter described. Fig. 3 is an inner side view of the ground-wheel hub. Fig. l is a View, partly in elevation and partly in section, showing a vehicle ground-wheel having my improved powertransmitting mechanism thereon; and Fig. 5 is an inner face View of the ratchet-wheel shown in Fig. 2.

Similar numerals refer to similar part throughout the several Views.

The mechanism hereinafter described is designed particularly to contribute rotary n10-v tion to a chain or belt carrying wheel from the ground-wheel of a wagon for the purpose of transmitting motion to mechanism carried on the wagon; but in the illustration and description I will confine myself to the means of imparting motion to the power-wheel, as it is obvious that various gear connections might be provided between the mechanism carried by the wagon and said power-wheel.

1 represents the ground-wheel of a wagon or other vehicle, this ground-wheel being formed with a central hub portion 2, the latter having an inward projection terminating in a cup-like casing or body 3. At diametrically-opposite points within said cup projection 3 and adjacent to the inner circular wall thereof I pivot the inner ends of pawls or dogs 4, the engaging points or outer ends of which are normally projected inward toward the hub-center through the medium of springstrips 5.

6 represents the horizontal axle or shaft, upon the outer spindle end of which is rotatably mounted the hub of the ground-wheel 1, said shaft or axle being in turn rotatably mounted in a bearing-box '7, which. depends from the under side of the vehicle-frame 8. Upon the axle or shaft 6 is keyed a ratchetwheel 9, the latter having its rear portion provided with an enlargement or circular flange 10. In constructing the body of the ratchet-wheel 9 I form the same on its outer face and about its central opening with a shallow outwardly-projecting neck 11, and on opposite sides of its neck portion I form the outer face of said ratchet-wheel with curved outwardly-projecting tooth-like lugs 12, each of the latter curving, as shown, to meet one of the notches formed by the teeth of said ratchet-wheel. Between the ratchetwheel and the hearing? I secure upon the shaft or axle 6 a power-wheel 13, which may, as indicated in the drawings, be in the nature of a sprocket-wheel adapted to receive a chain belt or which may be in the nature of a suitable gear or belt wheel. In slipping the ground-Wheel 1 onto the outer end portion of the axle or shaft 6 and at the same time causing the cup-like hub projection 3 to incase the ratchet-wheel 9 it is obvious that the forwardly-projectin g pawls or dogs 4 will by contact with the face of the ratchet-wheel operate to prevent the complete insertion of said ratchet-wheel or such insertion as to insure the engagement of the pawls with a tooth thereof. It is obvious, however, that by a partial rotation of the wheel the inwardlyprojecting pawls will be brought into contact with the curved guide-lugs 12 of the ratchet-whee], and through the latter said pawls will be guided outward into positions permitting them to drop into engagement with the ratchet-teeth when the groundwheel is pressed farther inward.

From the construction herein described it will be readily understood that the rotation of the ground-wheel imparted by the travel-' ing movement of the vehicle and the engagement of the pawls with the teeth of the ratchet-wheel must result in the rotation of the shaft or axle 6 and in a consequent rotation of the power-wheel 13. It is obvious, however, that when a reversed rotation is imparted to the ground-Wheel that the pawl ends will slip over the teeth of the ratchetwheel and prevent a rotation of said powerwheel.

It will be seen from the construction and operation herein shown and described that simple, reliable, and effective means are provided for transmitting power from the groundwheels of a wagon or other vehicle to a powerwheel and that through this operation mechanism carried by the wagon may have desirable motion imparted thereto.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a mechanism for transmitting power from vehicle-wheels, the combination with a journaled axle 6, a ground-wheel rotatably mounted thereon, said ground-wheel having a cup-like inward projection and spring-actuated pawls pivoted Within said cup projection, of a ratchet-wheel keyed on said axle and adapted to be received by said cup projection and to be engaged by said pawls and a power-wheel 13, carried by said axle, substantially as specified.

2. In a mechanism for transmitting power from vehicle ground-wheels, the combination with the journaled axle 6, a ground-wheel rotatably mounted thereon, said ground-whee1 having a cup-like inward projection 3 and spring-actuated pawls within said cup projection, of a ratchet-wheel carried on said axle 6, said ratchet-wheel adapted to be received by said cup projection and having formed on its face and on opposite sides of its central opening curved guide-lugs 12 each leading to a tooth-notch of said wheel and a power-wheel13 carried on said axle 6, substantially as specified.
